The Fuel
Saver. Field's Oil Vent Damper.
|
Field
Controls, the venting solutions
company, has developed a new Oil
Vent Damper that significantly
reduces off cycle heat loss in oil
burning appliances, resulting in
less fuel consumption, a 5% to 10%
savings in energy costs, and an up
to 2% gain in AFUE.
Normally, when the thermostat is
satisfied and the burner shuts
down, the residual heat in the
burner chamber escapes via the
chimney. The Field Oil Vent Damper
prevents this loss by effectively
closing the vent during the off
cycle. Field testing indicates the
average homeowner can save 5% to
10% on fuel costs with a properly
installed OVD.
The OVD also improves comfort by
reducing or eliminating drafting
through the chimney, which can
cause drafty conditions in the
living space.
The unit is installed between the
draft control and the vent outlet
and wired into the 120v primary
circuit or aquastat. When there is
a call for heat, the damper opens
within five seconds. Redundant 10
amp switches are wired in series
with the burner and will not allow
the burner to start until the
damper is open. Additional safety
is included with a 200 degree
WMO-1 blocked-vent safety switch.
In the event of a blocked chimney
or venter, the WMO-1 will shut the
burner down and prevent operation
until the vent is cleared and the
switch is manually reset.
A hold-open service switch is
included to lock the damper in the
open position during service or
maintenance. The housing and
damper are made of corrosion
resistant 316 stainless steel. The
damper plate rotates 360 degrees
for automatic self-cleaning
action.
